Description

Technical Field

[0001] This utility model relates to the field of magnetic powder clutch technology, specifically to a leakage-proof magnetic powder clutch. Background Technology

[0003] Magnetic powder clutches require lubrication with lubricating oil during use. However, there is an occasional possibility of lubricating oil leakage at the connection between the magnetic powder clutch and the rotor. This lubricating oil can drip onto the ground, polluting the environment and affecting its use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a leak-proof magnetic powder clutch to solve the problem mentioned in the background art that lubricating oil may occasionally leak at the connection between the magnetic powder clutch and the rotor, and this lubricating oil will drip onto the ground, polluting the environment and affecting its use.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a leakage-proof magnetic powder clutch, comprising a clutch body, a rotor disposed inside the clutch body, a fixed arc plate disposed below the connection between the rotor and the clutch body, a limit mechanism disposed at the inner end of the fixed arc plate, and an oil receiving box disposed at one end of the limit mechanism;

[0008] Preferably, the limiting mechanism includes a fixed cylinder, a return spring, and a limiting rod. Fixed cylinders are installed at both ends inside the fixed arc plate, and a return spring is installed inside the fixed cylinder. A limiting rod is installed at one end of the return spring, and the limiting rod can fix the oil receiving box with elastic force.

[0009] Preferably, guide plates are installed at the left and right ends above the oil receiving box, and baffles are installed at both ends of the guide plates.

[0010] Preferably, a heat sink is installed on the outer end of the clutch body, and an air inlet is provided on the outer end of the heat sink.

[0011] Preferably, an air intake filter is installed inside the air intake, and a cooling fan is installed inside the heat sink.

[0012] Preferably, the upper end of the heat sink is provided with a heat dissipation vent one, and the lower end of the heat sink is provided with a heat dissipation vent two, and a dustproof mesh is installed inside both the heat dissipation vent one and the heat dissipation vent two.

[0013] Preferably, the aforementioned.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This leak-proof magnetic powder clutch features an oil receiving box. When lubricating oil leaks from the rotor connection, the guide plate catches the oil and directs it into the receiving box for storage, preventing oil from dripping onto the ground and becoming difficult to clean. Simply empty the oil from the receiving box periodically. During installation, the limiting mechanism, consisting of a fixed cylinder, a return spring, and a limiting rod, pushes the receiving box into the fixed arc plate, causing it to press against the limiting rod. This compresses the return spring. Once the receiving box is in place, the return spring moves the limiting rod back to its original position, securing the receiving box. To empty the oil, simply pull out the receiving box. This convenient assembly and disassembly enhances the practicality of the leak-proof magnetic powder clutch.

[0016] 2. This leak-proof magnetic powder clutch can activate a cooling fan during clutch operation, causing the fan to rotate and draw in cool outside air from the air inlet into the heat sink. The air is then blown out from heat sink 1 and heat sink 2, thus carrying away heat and rapidly cooling the magnetic powder clutch. This prevents the magnetic powder clutch from overheating and affecting its use. The air inlet filter prevents dust from entering the heat sink and affecting heat dissipation, further improving the heat dissipation effect of the leak-proof magnetic powder clutch.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A leak-proof magnetic powder clutch includes a clutch body 1, a rotor 2 is disposed inside the clutch body 1, a fixed arc plate 3 is disposed below the connection between the rotor 2 and the clutch body 1, a limit mechanism is disposed at the inner end of the fixed arc plate 3, and an oil receiving box 4 is disposed at one end of the limit mechanism.

[0025] In this embodiment, the preferred limiting mechanism includes a fixed cylinder 5, a return spring 6, and a limiting rod 7. The fixed cylinder 5 is installed at both ends inside the fixed arc plate 3, the return spring 6 is installed inside the fixed cylinder 5, and the limiting rod 7 is installed at one end of the return spring 6. The limiting rod 7 can fix the oil receiving box 4 with elastic force.

[0026] In this embodiment, guide plates 8 are preferably installed on the left and right ends above the oil receiving box 4, and baffles 9 are installed on both ends of the guide plates 8.

[0027] In this embodiment, a heat sink 10 is preferably installed on the outer end of the clutch body 1, and an air inlet 11 is provided on the outer end of the heat sink 10.

[0028] In this embodiment, an air intake filter 12 is preferably installed inside the air intake 11, and a cooling fan 13 is installed inside the heat sink 10.

[0029] In this embodiment, the upper end of the preferred heat sink 10 is provided with a heat dissipation port 14, and the lower end of the heat sink 10 is provided with a heat dissipation port 15. Both the heat dissipation port 14 and the heat dissipation port 15 are equipped with dustproof nets.

[0030] In this embodiment, the anti-leakage magnetic powder clutch utilizes an oil receiving box 4. When lubricating oil leaks from the rotor 2 connection, the guide plate 8 collects the oil and directs it into the oil receiving box 4 for storage, preventing oil from dripping onto the ground and becoming difficult to clean. Simply empty the oil from the receiving box 4 periodically. During installation, the limiting mechanism, consisting of a fixed cylinder 5, a return spring 6, and a limiting rod 7, first pushes the oil receiving box 4 into the fixed arc plate 3, causing the oil receiving box 4 to press against the limiting rod 7, thus retracting the return spring 6. When the oil receiving box 4 is installed... After positioning, the return spring 6 drives the limit rod 7 to reset, thereby squeezing the oil receiving box 4 for fixation. When emptying oil, the oil receiving box 4 can be pulled out. When the clutch is running, the cooling fan 13 can be started to make the cooling fan 13 rotate, thereby drawing cold air from the outside into the heat sink 10 through the air inlet 11, and then blowing it out from the heat sink 14 and the heat sink 15, thereby taking away the heat and cooling the magnetic powder clutch quickly, avoiding the magnetic powder clutch from overheating and affecting its use. The air inlet filter 12 can prevent dust from entering the heat sink 10 and affecting heat dissipation.

[0031] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
